If a , b, and c are in Arithmetic Progression, then the straight line ax + by + c = 0 will always pass through the point:
a) ( 1, 2)
b) (1, 2)
c) (1 , 2)
d) (1, 2)

Best ResponseYou've already chosen the best response.0we should know that the slope of the line is: a/b

Best ResponseYou've already chosen the best response.00 = a/b x  c is then what we have to conform to i believe

Best ResponseYou've already chosen the best response.0well, c/b on the end i spose would be more accurate

Best ResponseYou've already chosen the best response.0when x=0, c/b = 0 means that c=0 so: y = a/b x seems like a fair assumption

Best ResponseYou've already chosen the best response.0ax +by + c = 0 ax + by = c y = (ax c) /b no zero involved .....

Best ResponseYou've already chosen the best response.2If a, b and c are in AP, then doesn't this imply: b = a + d c = a + 2d where d is the difference between each term of the AP?

Best ResponseYou've already chosen the best response.0if my line equation is useful; maybe sub in so that it all speaks in a?

Best ResponseYou've already chosen the best response.2Then you can rewrite your equation as: ax + (a+d)y + a + 2d = 0 and see for which point this equation holds true?

Best ResponseYou've already chosen the best response.0\[y = \frac{ax (a+2d)}{a+d}\] would be the same set up i believe

Best ResponseYou've already chosen the best response.0a) ( 1, 2) b) (1, 2) c) (1 , 2) d) (1, 2) trial and error .... \[2 \ =^? \frac{a (a+2d)}{a+d}\] \[2 \ =^? \frac{a (a+2d)}{a+d}\] \[2 \ =^? \frac{a (a+2d)}{a+d}\] \[2 \ =^? \frac{a (a+2d)}{a+d}\]

Best ResponseYou've already chosen the best response.0Is it? I wrote (1, 2), just guessing.

Best ResponseYou've already chosen the best response.0i got a typo in my cerbral cortex; :) 1,2 might be better; would have to test it out
